The binomial cumulative probability with p=0.5 for 3+ successes is as follows:

for p=0.5 (50% success rate) it becomes:

the probability is 0.65625, or about 66%
Answer:
0.50 x 4.50 = 69.42.00 and 22 = 47.420.00
Step-by-step explanation:
47.420.00
2•10+5•3
10•3
35/30*5 ( do it on both sides )
you'll get 7/6 or 1 1/6
First compute the coefficient like this:

Simplifying the fraction over 4! we get:

and the variables are

. So answer

.
The correct answer is C then.
